Probing quantum mechanics using nanoparticle Schrödinger cats
Sebastian Pedalino, Bruno E. RamÃrez-Galindo, Richard Ferstl +3
The quantum superposition principle is a cornerstone of physics and at the heart of many quantum technologies. Yet, it is still often regarded counterintuitive because we do not ob…
Desorption-induced decoherence of nanoparticle motion
Jonas Schäfer, Benjamin A. Stickler, Klaus Hornberger
We derive the quantum master equation predicting how the translational and rotational dynamics of a nanoparticle is affected by the emission of surface adsorbates. This is motivate…
Probing molecular photophysics in a matter-wave interferometer
Lukas Martinetz, Benjamin A. Stickler, Ksenija SimonoviÄ +4
We show that matter-wave diffraction off a single standing laser wave can be used as an accurate measurement scheme for photophysical molecular parameters. These include state-depe…
Decoherence of dielectric particles by thermal emission
Jonas Schäfer, Benjamin A. Stickler, Klaus Hornberger
Levitated nanoparticles are a promising platform for sensing applications and for macroscopic quantum experiments. While the nanoparticles' motional temperatures can be reduced to…
Probing rotational decoherence with a trapped-ion planar rotor
Neil Glikin, Benjamin A. Stickler, Ryan Tollefsen +5
The quantum rotor is one of the simplest model systems in quantum mechanics, but only in recent years has theoretical work revealed general fundamental scaling laws for its decoher…
Quantum Optical Binding of Nanoscale Particles
Henning Rudolph, UroÅ¡ DeliÄ, Klaus Hornberger +1
Optical binding refers to the light-induced interaction between two or more objects illuminated by laser fields. The high tunability of the strength, sign, and reciprocity of this…
